Text Box: What is Chipless RFID?
A chipless RFID is a fully printable passive microwave circuit that responds to an interrogating signal with a pre-defined frequency, time and hybrid-domain signatures. Since the tag has no application specific integrated circuit (ASIC), the cost of the tag is comparable to the optical barcode.
Text Box: What is unique about Chipless RFID?
A chipless RFID has the potential to remove and\or co-exists optical barcodes. The tag can also offer flexibility like a chipped tag. It can also be directly printed on paper and plastic. It is called smart labels.
Text Box: What type of reader is needed for Chipless RFID?
A dedicated reader is designed to read a specific chipless tag. Since the tag is fully dumb-contains no intelligence chipset, the reader contains all signal processing and intelligence capabilities. Based on frequency, time and hybrid domain tag types, readers are designed. Conventional anit-collision and hand-shaking algorithm cannot be used in chipless tag system. 
Text Box: What type of Chipless tag MMARS has developed?
MMARS pioneered in developing frequency signature based chipless tag in both microwave and mm-wave frequency bands. Gen1 tag is a dual-polarised stopband multi-resonator filter also called re-transmission tag. A mm-wave back-scattering chipless tag is also developed with 29-bit data capacity. A time-domain tag is also designed based on TDR principle. Two patent applications are filed on the invention. Four books, twenty six book chapters, approximately one hundred fifty refereed journal and conference papers are published in the field.
